Money Market Funds UK: Low-Risk Returns Better Than Savings Accounts?

SYM

Money market funds (MMFs) are low-risk investments that hold very short-term debt (government bonds, bank deposits, corporate paper). They aim to maintain a stable value while generating returns slightly better than cash. In 2024–2026, with the Bank of England base rate elevated, UK MMFs have been outperforming many easy-access savings accounts. But are they safe?

How Money Market Funds Work

MMFs pool investors' money and invest it in very short-duration, high-quality assets: UK government gilts, T-Bills, bank deposits, and investment-grade commercial paper maturing in days to months. They aim to maintain a stable £1 per unit value (constant NAV) or fluctuate minimally (variable NAV). Daily returns reflect overnight money market rates — essentially closely tracking the Bank of England base rate.

Returns vs Savings Accounts

In 2025–2026 with the base rate around 4–4.75%, popular UK MMFs (Vanguard Sterling Short-Term Money Market, LGIM Sterling Liquidity) have been yielding 4–4.7% gross. Many easy-access savings accounts offer similar rates, but fixed-term accounts locking money for 1–2 years are needed to match MMF returns without lock-in. MMFs offer daily liquidity — no notice period, no fixed term. The trade-off is no FSCS protection.
  • •Easy-access savings accounts (2026): ~4.0–5.0% AER
  • •UK MMFs (2026): ~4.0–4.7% gross yield
  • •FSCS protection: savings accounts yes (up to £85,000), MMFs no
  • •Access: both offer same-day or next-day liquidity

Risk: Is Your Money Safe?

MMFs are significantly safer than stock funds but carry more risk than FSCS-protected savings accounts. In theory, a MMF could 'break the buck' (fall below £1/unit) if underlying assets default or face a liquidity crisis — this happened rarely during the 2008 financial crisis in the US. UK-regulated MMFs invest in high-quality assets with very short maturities, making this extremely unlikely. However, they're not covered by FSCS protection.
How do I invest in a UK money market fund?+

Most UK investment platforms (Vanguard Investor, Fidelity, Hargreaves Lansdown) offer MMFs. They can be held in an ISA or general investment account. Check the OCF (ongoing charges figure) — it should be very low (0.10–0.15%).

Are money market fund returns taxable?+

Yes — income from MMFs is taxable as interest (not capital gains). Hold them in a Cash ISA or Stocks and Shares ISA to make returns tax-free.

When to Use a Money Market Fund

MMFs make sense for: emergency funds for those with large savings (above the FSCS £85,000 limit per institution), short-term parking of cash while deciding what to invest in, businesses holding working capital, and investors who've sold investments and are waiting to redeploy them. For most personal savers with under £85,000, FSCS-protected easy-access accounts with competitive rates are simpler and arguably safer.
